Seasons are labelled by harvest year (April–October). Year-to-year changes from ERA5-Land; tested against station records in Alto Adige (r = 0.94 for season temperature at Bolzano). Rain varies more locally, so treat single-season rain with some caution. Vintage ratings, harvest dates and frost or hail events have places in the data model but are not loaded yet.

- Generated from EU reference data: check against the current product specification.
- From the specification: DOCG. Vinification and bottling may take place anywhere in the province of Ragusa and in listed communes of Caltanissetta and Catania provinces, so the in-zone requirement is left null. Vineyards qualify only from their third year of production.
